JOSEPH SEVERSON, 0F OZONE PARK, LONG ISLAND, NEW YORK NUMBERING FIXTURE.

Application filed June 17, 1920. Serial No. 389,680.

To aZZ whom it may concern:

Be it known that I, Josnrrr SnvnRsoN, a citizen of the Unitcc States, and resident of Ozone Park, Long island. county ot Queens, and State or" New York, have invented a new and Improved Numbering Fixture, of which the following is a full, clear, and exact description.

In connection with engraving machines utilized in applying engraving num. ers in various devices, it is well appreciated fact that the conventional machine usually in cludes a work block upon which engraving stylus is moved by means oi a pantw graph, a tracing stylus being associated with the pantograph which trzu stylus mov over the table adapted to recei e blocks, which as is well known, 1: rule slugs of metal bearing upon them a carefully engraved design representing a numeral, let ter, etc.

Heretoiore, when it has been desired to change the reading of these blocks, so that a different engraving might be applied, it

has been customary to release a set screw provided for this purpose, so that the blocks might be removed one by one, and substituted for the slugs desired.

This has been at best but cunlhersome expedient, in view ot the fact that it has been necessary for the operator to have a great number or substitute sluq s lying upon the work table before him, which slugs were liable to become misplaced, broken, etc.

Having these defects in mind. it is now an object of my invention to provide numbering fixture which is more particularly daptcd as a substitute for the master blocks heretofore utilized for this purpose, although this fixture might be applied to any desirable use.

A further object of my invention is the construction of a nun'ibcrii fixture, by means of which any suitable I'et'ercnce characters may be immediately presented. so that they may be utilized in opcrati u the tracing stylus, and which will turther be held against movement when the same are in correct position.

Reference is had to the attached sheets of drawings as illustrating one practical embodiment of my invention, and in which,

Figure 1 is a diagrammatic view of an engraving machine of the type specified, with my improved numbering fixture ap plied thereto.

115 nuister Figure 2 is a sectional end view taken along the lines 2-2 of Figure 3.

Figure 3 is a sectional side view taken along the lines 33 of Figure 2.

Figure at is a front view of a certain detail of numbering fixture.

Figure 5 is a side view of the same, partly in section, and taken along the lines '55 of Figure 2, and

Figure 6 illustrates a detail of numbering fixture.

In these views the reference numeral lO indicates a standard of an engraving machine which may beof the type illustrated in United States Patent 312,902 and which has a work block 11 associated therewith. Arranged above the work block 11 and adapted to travel over its surface is a conventional engraving stylus 12, which is moved by means of any desirable type of pantograph .13, operated by the tracing stylus 14; overlying the operating table 15, having applied thereto my improved type of fixture.

It is now customary, as aforestated, to mount the master blocks upon the operating table, and to clamp them thereon by means of a set screw. Upon different pieces 'to be serially numbered being positioned upon the work block 11, it has been necessary to loosen the set screw, and to each time substitute a different master block to produce the result desired. These blocks have subsequently dropped, become lost or broken, aside from the fact that a great amount of time was always required to properly remove and re-apply the desired block.

My numbering fixture, which aims to overcome these detects, now conveniently includes a U shaped bracket 16, which is preterably provided with a stud 17, which serves, by virtue of a co-operating screw 18 attached to the operating table'l5, to retain.

the numbering fixture in applied position.

The rod 19 preferably has its ends extending through the upper ends of the bracket l6,and serves as a medium whereby numbering fixtures maybe rotatably mounted. Each of these blocks conveniently includes a multtt'aced disk 20, having a reference character applied to each of its faces.

It will be understood, that by the construction provided, that the working table will at all times have applied to it, a num bering fixture presenting any desirable types,
